a) It would improve things because website owners, seo's or whatever you want to call them, always listen everything Google says. I'm in the industry. One tweet from Matt Cutts and they are already changing the brand name if Matt tells them so. That is the way industry works. Everyone knows site speed is a weak signal. Google could impose harsh penalties but they don't. b) Google has become really smart nowadays. You could theoretically game everything in this world. They execute the javascript and run the page, they already know how to detect banners, interstatials etc. They also have manual team giving out bans.
